Ta t/ll whom it may (am-era:

Be it known that I. Lenoir I). KELLoco, a

State of Illinois, have invented certain new and useful Improvementsinilgmtion and Lighting Switches, of which the'following is aspecification.

My invention rela-tes'to electrical switches and has more particularlyto do with combination liphting and ignition switches for' automobi es,such as are generally provided for control b the operator. Tie generalobject of my invention is to provide a unitary structure including botha lighting and an ignition control switch whichembodies desirablefeatures and advantages all in a simple, compact, eflicient andeconomical manner. Lighting and ignition switches of the type nowcommonly used, have two separate actuating members for operating theswitches; one for controlling the lighting circuit and the other forcontrolling theignitionicircuit, and they are generally provided withmore or less complicated locking means for. locking the switchesin theirdifferent desired positions. A special object of my invention is theprovision of a switch of the above type which eliminates this more orless complicated locking mechanism, but

which is so arranged "as to prevent its tion to another un switches frombeinp moved from one posiess the operator is provided with thenecessaryoperatmg means for performing this function. There are otherfeatures of .myinvention which will be more particularly pointed out inthe ensuing specification claims.

Referrin now more in general to the de-' I vice as il ustrated, switch Shavinfi in positions w lig h it comprises a light a normal and threeoperatereby three combinations of.

ts may be connected in circuit, the 'referred arrangement being suchthat w en the light switch is moved to its sition B, the side andrearlights are lig ted, when the'light switch is moved to its position 0,the head and rearlights are lighted, and

when the light switch is moved to its po'sition D, all of the'lights arethrown in.cir-' cuit. It is to be understood-that my invention'is notlimited to this particular combination of lights or to the fourpositions of the ignition circuit interrupted without affecting theposition of the lighting switch as will also more fnlly'hcreinafterdescribed in the ensuing specification.

,Wi'th this general understanding of my invention as illustrated, Iwillnow describe it more in'detail. A mounting late 1 is provided forcarrying a -rotatabe switch supporting member '55 as shown in Fiinia,which membercomprises a shaft 2 w ich carries a pair." 50f insulatinglymounted wipers 3 which are held apart although elec tricallyconnectedbya washer 4 the "said wipers and washerfhcing clamped n'pon theshaft bymeans of a nut 5 which has screw threaded enfgagementwvith the upperportion 'of the sha I I provide a device for ieldingly holdingthe lightswitch S in its iflerent operating positions, this device including anotched or serrated disk ,6 which is preferably integral with the' shaft2, and an arm 24 provided with a roller 25-ior co-operating with themember 6 in a manner to be morefully hereinafter described. To insurethat the relation between the disk (i-andwipers 3'rcmains the' shine; apin 7 is prov ded which is pressed through an insulating bushing in thedisks, the pin and bushing then through the wipers 3. The wipersextending are pre erably constructed of two parts 'electricall .umted bythe washer 4 as before Iii-" 8! afar-tummy shown "in Fl a, while thementions the up r wiper comprising 8* an the lower vwiper comapartsliand 3, the upper blades with a common se ent with 'tli e segments'fl 10and 11 most clearly shown in ig. -9. 'lhe segmerits 9, 10 and '11areconnected to the terminals 12, 13

' and 14-by means of screws 15, while the cum, ,mon segment 8 connectsto. the terminal '16 by means of clam ing screw 17. The light switch S,as a who e, is rotatably supported -.in an annular "orifice 18 in themounting late 1 and held against. longitudinal motion y means of anut'19 which has screw threaded engagement with the lower portion ofethe shaft 2. The segments 9, 10 and 11 are .insulatingly mounted on theplate 1 by means of the screws 15, and the common segment 8 is supportedby studs 20, 21 and held in place by means of the insulated clampingscrews 17. In Fi 12, I have illustratedthe manner inwhic a se ment as 9,is connectggi to its rear termin' this figureheifi'ga section along line12,12 of Fig. 4. The segment 9 is insulated from the plate 1 by means ofthe insulation block 22 and conncted to the terminal 12 by means of thepcrews 15. -'The said terminal 12 is also insulated from the mountingplate L by means ofthe insulation strip 23. With the light switch wipersin their normal msitiou A, there is no effective connection etween .thecontact segments of the switch, but when it is moved to the position B,segments 8. 9 and 10 are connectedas indicated in Figs.

8'and 9 giving one combination of lights.

-- Now, if'the light, switch is moved to itsposition C, contact segments8,10 and 11 areconnected as indicated in Figs. 8 and 9 grvuig a secondcombination of lights, the segment 9 has its right end position cut,away so that when the light switch is in position 0 the wipexsrest overso cut 9 ut do, not make contact therewit as is clearlyshown m Fig. 6,if theulie'ht switch art,

switch in any of its'plurality 'of operative positions, 1' providesholding device H comprising an arm 24 carrying a rotatable roller 25'adapted to co-operate with the serrated disk 6, the said arm beingpivotally supported at its other end by means of the ,stud 26 carried bythe. plate 1." A spring member 27 rests upon the connecting bridge 28 ofthe arm 2i and this spring presses the roller 25 against the disk 6 sothat when -the light switch is operated a tooth of' the notched disk 6presses against the roller 25 forcing it outwardly against the action ofthe spring 27, and as the disk advunces,.tl1e

'roller .acts upon-the opposite face of the 'tooth to give a quick snapaction to the switch, and thereafter 0 rates to maintain the switch inits operate position.

Referring now to the ignition switch IS, it comprises resilient springmembers 30 and 31 insulatiri'glymounted upon a tripod 32 which isfastened tothe. mounting plate 1 in. any suitable manner as by means ofthe screws 33. Suitable terminals 34 are provided for'the" resilientspring members 30 and 31. I provide a casing 35 in the form of acylindrical tube for enclosing'the switch appanatus, the said casing 35also forming the' supporting means forthe mounting plate 1. I The 'plate1 has a plurality of earsr ifi struek'np at right angles to the face ofsaid plate 1, the said cars 36 aligning with suitable slots 37 cut intheorising 35 so that when the mounting plate 1 is inserted into theeaslag-35, the port-ion 36 ofthe cars 36 enter the slots 37 in 'thecasing 35. Suitable holes are provided in the ears 36 to receive screws38 which have screw threaded engagement with tapped and threaded holes39 in'the casing 35, thus securely holding the lighting and-i nitionswitches as a unit in the casing 3: cap -16 15 provided for enclosingthe lOWQIPOl'tIOH of the swltch structure and is held in place upon thecasing 35 by means of screws 52. The cap is also provided with anopenmgfitl' through which leads arecxtendcd from the terminals of .theswitches. A

front'mounting plateiO is provided which fits over the opposite end ofcasing 35 and is provided with an integrally formed flange 40 forsecuring the device as a unit to any desirable mounting member. The'cap40 is fastened to the gasigg by means of the screws 41, and encloses theupper,por'tion. vof'the f switch as a whole. The cap 4fl salso proyided1witlala clpllar 43 whosejoentratlfignfics .1 p e x g l in pej .i ,gfei. a being rotatably mounted in annular'oritigein the ca manysuitablfijm' ner,as.i-;inosfi;clearly by spun over the-ooverroftheandits' other end spun over a w a9, ichhi slinserted between the ca theq-igpun'portion of the collar 43.- oo

an 'actuatin shaft orke -45 which isvtused to operate t e light and alsoused to control the ignition switch as will be described. i

The actuating plunger 45 is divided into three portions the upperportion 45 being preferably hexagonal in shape co-operating with thecollar 43 which is rotatably secured to the cap 40, the central portion45 being square in sha and co-operating with a rectang'ularori cein theshaft of the light switch while its oppositeend 45 is adapted toco-operate with the ignition springs- 25 and 31. The hexagonal portion45 of the key 45 has an indicating arrow 47 fastened thereto in anysuitable manner as by means of a pin 48, the arrow serving the purposeof indicatin the different operative positions 50 of the lig t switch,namely oil, side and rear, etc, thus enabling the operator to see at aglance which combination of lights is in use. The end of the hexagonalportion of the key is threaded to receive a knob 50 .35 whichfacilitates the turning of the key to rotate the light switch to itsdifierent operative positions. The shaft 2 of the light,

switch S has a square orifice extending the length of the said 'shaftone side of which is provided with a bead or rib 51 extending the alength of the opening, the square portion of the key 45 h ving a grooveor slot 53' of a size and shape to receive the bead 51 of the squareopening of the light switch shaft.

45 The oposite end of the key 45 has an insulating annular button 54attached to it and next to it a metallic ring 55 suitably insulated fromthe key, which co-operates with the ignition springs 30 and 31.- v pReferring now to Fig. '3, the key 45 is shown in its operative position,that is, the metallic ring is in contact with the ignitionsprings 30 and31 thus closin the cir- -cuit of the-ignition apparatus. he light 55switch is so arran that it may be moved .to any of its p'ositipnswithout affecting the ignition circuit.

, To move the said-lighting switch S\into any one of its plurality ofpositions the c athe operator'grasps the knob 50 and rotates "it-Lin thedirection to light any particular combination of lights, that isdesired. The

. movement of the key 45 rotates the wipers 3 Zinto engagement with thedifierent segments fii'to close circuit, arrangements to give thecombinationof lights desired. The light Sis' held in its operatedposition by longitudinally move the key 5 until the portion 54 isbrought between the springs 30 and 31. The ignition circuit is thusopened but the light switch S will be held in its position due to theyielding holding device H. Should the operator desire to leave his carstand at any place for any length of time, he disassociates theactuating member or key 45 from its casing by entirely removing ittherefrom, thereby opening the ignition switch while permitting thelighb ing switch to remain in any desired position. When the plug isremoved the ignition switch is inaccessible to any person other than theone provided with the proper combination key. The lighting switch isalso rendered inaccessible to any other than the operator provided withthe proper key. The

bead 51 and groove 53 in the shaft 2 and the. portion 451 of the key 45respectively provide means so that upon the reinsertion of the key theoperator will always be able to place the key back into the light switchin the same position as it was at the time of withdrawal, and the arrowwill oint. to the combination that is lighted. hen the key is insertedinto the collar 43, the'operator rotates the key, due to the rdtatablecollar 43 until the groove 53 in the poition 45 of the key 45 coincideswith the head 51 in the shaft 2 of the light syvitch and when the key isin 10 this position it may be further :longitudi nally operated to bringthe portion 54 of the key into operative relation with the springs 30and 31. The grooves in the members 54 and 55 co-operate with the roundedend portion of the s rings 30 and 31 to provide means for yie dinglyholding the actuating member a ainst longitudinal movement, therebyholding the ignition switch in its on or of! position.

From the above it may be seen that the lights of the car may remain incircuit and at i the same time the circuit of the ignition apparatus maybe opened and the actuating members disassociated from the rest of theswitch so as to prevent tampering with the same. \Vith my improvedswitch, I do away with many compilicated parts, this producing a-switchsimple in construcilon and most efiicient as a lighting and ignitionj13o switch, cheap in its construction and at the same time a positivelock against operation by other than the operator. It is of courseunderstood that many different sizes and shaped actuating members may beused thereby giving an infinite number of combinations without departingfrom the scope of my invention; It is also apparent that the actuatingmember may be provided with a greater number of irregularly shapedsections for co-o ration with an equal number of similarly slizpedapertures respectively.

In illustrating my invention I have chosen a preferred form but it is tobe understood that many chan es and modifications will readily suggest temselves, and I therefore do not desire to be limited to the exactstructure as shown but aim to cover all such changes and modificationsas come within the spirit and scope of the appended claims.
